Specification of Letters Patent.

Patented June 13, 1916.

Application filed October 31, 1913. Serial No. 798,548.

To all whom it may concern Be it known that we, IVJZLLIAM J. CARR andGEORGE F. HUTOHINGS, citizens of the United States, and residents ofKansas City, in the county of Jackson and State of Missouri, haveinvented a new and useful I-mprovement in Envelops, of which thefollowing is a specification.

Our invention is an improvement in envelops, and has for its object toprovide an envelop which is ,capable of more than one use, the envelopbeing so arranged that it may be used many times, without destroying thesame.

In the drawings, Figure 1 is a front View of an embodiment of theinvention, Fig. 2 is a front view of the envelop shown in Fig. l, inopen condition, Fig. 3 is a section on the line 33 of Fig. 1, looking inthe direction of the arrows, and Fig. 4 is a detail view of the sealingstrip shown in Fig. 1.

The embodiment of the invention shown in Figs. 1, 2, and 3 is formedfrom a sheet of paper of suitable size and weight, and cut to the formdesired. The said blank is cut and creased to form a central fold 15,and lateral folds 16 and 17 each of the lateral folds 16 and 17 having asealing flap 18 and 19, respectively, at the side edge remote from thecentral flap 15. In addition the lateral fold 16 is provided with endflaps 20. The flaps 16 and 17 are also provided with elongated,substantially elliptical openings 21 and 22 respectively. In addition aslot is out between each of the lateral flaps and the adjacent sealingflap, the said slots being designated by reference characters 23 and 24respectively. The central flap 15 is provided with a pair of parallel,longitudinally extending, laterally spaced slots 25 at'approximately itscenter, the said slots being parallel with the slots 23 and 24: andbeing of equal length. After the blank has been cut and creased as abovespecified, the lateral flaps or folds -16 and 17 are folded over onopposite faces of the central flap 15 after which each of the sealingflaps 18 and 19 are folded down upon the outer face of the oppositelateral flap or fold. The inclosure is completed by folding over the endflaps 20 on the outer face of the lateral flap 17.

The sealing strip shown in Fig. 4 and used to close the envelop shown isof a length correspoi'iding to the size of the envelop with which it isto be used, and the said strip is preferably of the same paper as theenvelop which it is intended to, seal. The strip is creased transverselyto form three equal portions 26, 27, and 28 respectively. To seal theinclosure shown in l, the strip is passed through the slots 6 and 5 withthe portion 27 of the strip inside the envelop, that is, between thebody 1 and the fold 2, and the sealing strip 3 may be folded between thebody 1 and the fold 2, or on the outer face of the fold 2. After beingso arranged the end portions 26 and 28 are folded down upon each other,the portion 29 being beneath the portion 26, and the portion 26 issealed to the portion 28. To open the envelop the sealing strip is cutat the junction between portions 27 and 26 or at the junction betweenportions 27 and 28, and the entire strip is removed.

In the construction shown in Figs. 1, 2, and 3, two receptacles areprovided. The said construction, when not in use, will show twoaddresses, one on either face, but when in use, one of the addresses,namely, that not required is covered, the envelop being especiallyintended for reciprocal correspondence.

We claim:
